ToaZl whom 'it may concern: 1

Be it known that I, WALTERfItKEN'NEDY, a citizen of the'Unitedl States,jresiding at Grand Rapids, in the'countyfof Kent and State of Michi an, have invented certain new and useful mprovements in' Valves, of which the followi is a specification.

Myinventio'n re ates'to improvements in'v automatic valves of the'classv described and claimed in .Letters Patent number 867 ,139', issued to me Sept. 24, 1907and its objects are: First, to provide a valve with which 'the inilow pipe and valve may besituated directlyppposite, and in alinement with the outflow plpe; Second, to provide forcenducting as, &c., to the main outflow pipe e and to t e outflow pipe that leads to vt pilot light, by separate and independent channels, and, third,l to provide a means whereby the intlow valve may be locked to the desired position. I attain these objects by the mechanism illustrated in the accompanying drawing, in which J Figure 1 is a longitudinal section of the valve on the line y y of-Fig. 5. Figs. 2 and 3 are modiiied forms of the' same. Fig. 4 is a plan of the plug of the valve detached from .the barrel, and, Fig. 5 is a transverse section of the kplug andthe bearin portion ofthe barrel, on the line X X of l'lg. 2, with the plug turned around so .that the slots 4for the passage of gas are closed and gas cannot pass-through them.

lSimilar letters refer to similar throughout the several views.

This valve is constructed with a barrel A parts having a conical portion oropening for the.

reception ofthe conical plug B, andan o ening eading therefrom forthe passage ofp the stem B', and at the large end a chamber A is formed' by the walls of' the barrel, the large end of the lu B and the inner end of plug A revo ub e valve G is located in the bearing. G, and so arranged that by turning it the passage y maybe lopened' andl closed at pleasure, and directly opposite from this-.valve is located thedischarge pipe .C having a small longitudinalaperture c through which gas may be allowed to escape from 'the chamber A', when allowed to enter' said chamber by theproper adjustment of the valve G. The passage from the valve G to and throughthe chamber'A may be in anyone of several ways,l as for instance:`

out through the `passage way c in the eut'-A flow pipe C. In Fig. 2 the passage way j,

. rat-antec Aug. 4, 190s. i

B andthe'nce-the lon 'tudinal passage way passing thr'ough the valve G and the side of the barrel A, Opens directly intothe passage way a', which, in this case; is made to `pass1 beyond the line of the passage vwayl j, and thence throu h the registering passa e way 1b to the cham er A, and thence out It rou the passage ways b.a l to and through t e passage Way ein the pipe C, to a gas burner or any other desired point, whilein Flgz the passage way jis made to pass throughA the valve G forming a rightnangle, and an independent passage way 7c `is formed to o en from the valve G into the chamber A t rough lthe port' hole le whence gas may' pass out through the passage wa s b b', aa and the groove b that connects t e passageways a a', to `andthrough the jpassage way c.

D represents a lever that projects out at right angles from the stem B and is provided .with a passageway d that registers with the passage Way '1,' in the stem, and is designed to yconvey gas from the valve G to a pilot"light located in any desired' position. The passage Wayfi extends, longitudinal of the `stern B to a position near the small end of the plug B where it' vpasses through theside of the" stern in position to register with thel passage -Way/i in the barrel A, which is deslgned to register with the small by-pass' g in the valve Gr"k so that gas passing through the passage Way j? will be diverted to the passage Ways t, 'i' and d, ashereinbefore described. I have formed a short diverging chamber at g and at the end of the by pass g"` so that if the valve G is turned in the direction of the -ar- .v rows in Figs. 1 and 3, suiiiciently to clit off either of said passageways, otherwise it" would be impossible to cut off the flowof gas when desired or necessary.

The grooves b' should be so formed as to avert all danger of forming shoulders or un even places in the bearings between the plug B and the barrel A by the constant motion of the plug when oscillating 'to open and close the passage ways a a, b b to regulate the flow of gas to the gas burner. i

In Fig. 5 I have shown the passage ways a and b offset so that no gas can pass through them, and to cause them to register so thatl gas may pass through, it is simpl.v necessary to turn the plug B in the direction of the arrow in said figure, which is accomplished by pressing down upon the end of the arm D, and the plug is forced back to normal posi-A tion by means of a suitably adjusted spring, as F, in the chamber A or in any other availl able position.

To insure the placing and holding of the valve G' to the propler position to cause the passage way throug the valve and the side of the barrel to properly register to allow the gas to flow freely through `the barrel, to shut it off from the barrel and yet allow it to flow through the passage Way i t', or to close all passageways and shut ofi` the ow of gas entirely, I place any available form of lever, as L, pivoted at Zto the lever L so that the end Vmay' be made to engage the notch Z" that will hold the valve to the desiredposition, and for this purpose anyv available form of lever or catch may be used.

J represents a piece. of the main line of gas pipe leading into the valve, and I represents a screw by means of which the flow ofgas through the arm D may be regulated and 7c" represents a fcrew designed to close the end of the passage way 7c so that gas cannot escape therefrom except as it asses through the port hole k' into the cham er A', as herei -inbefore described. 4H merely represents a packing box or nut designed to prevent gas om escaping through the barrel around the stem B'. f

When the groove b' is made in both the surface of the barrel A and of the plug B it is desirable that they be so arranged that they will lap by each other a littleso that there will be no danger of forming shoulders at the linesof contact, or, in other words, so that there will be no lines of contact where a-shoulder can be formed.

When the construction shown in Fig. 2 is used the slots a' must be ma'de lar-ge enough to insure a sufficient flow of gas to the chamber A', and the groove b' will only connect the several other slots, or, in other words, will allow the gas that has passed through the groove a and its adjacent or registering groove b to the chamber A', to pass down through the several slots b in the plug that register with the slots a a in the barrel and thence through the passageway c. In Fig. 4 I have shown this construction of the groove b' in the plug B.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is:

'1. In combination with a barrel having a conical inner chamber with longitudinal slots in a portion of its surface, a taperin plug within said barrel having longitudina slots in position to be made to register with the slots in the surface of the barrel and an i annular groove connecting the longitudinal slots, a hollow stem `integral with the plug, and a hollow arm at right angles with the stem and in position so that the hollow in each will register with the other; an inflow pi e and cut off valve at one side of the barre, an4 outflow pipe projecting from the other side of the barrel directly opposite from the inflow pi e and having passageways through the barre and plug from the inflow ipe to the outflow pipe, the valve having a y pass-registering with the hollow in the stem, and a catch connected with the cutofl valve in position to lock this valve to the desired position.

2. `In combination, a valve com osed of a barrel, a lug fitted into the barrel ongitudinally an forming a chamber in one end of the barrel, an actuating spring in said chamber, an inflow pipe andan outflow pipe on directly opposite sides of the barrel with .passage wa s formed from the inflow pipe ongitudina ly through the valve and back to the outflow pipe, a stem integral with the plug an arm at right angles with the stem each having a passageway registering with the-other, a cut ofi valve in the inflow pipe andhaving a by pass made to register with 4the passageway in the stem, and means for locking the cut-off valve to position.

3. In combination with a longitudinal barrel, a lug therein with-longitudinal passage Ways between them, an inflow pipe and an outflow pipe at right angles wit i and in direct alinement on opposite sides cf the barrel, with passage ways formed to register withthe passageways in the valve, a stem integral with the plug and having a passage way through it, an arm secured at right an- 'gles to the stem and having a passage way way to register with the passage Way in the Signed at Grano.
